[QUOTE="Gunpoor, post: 935802, member: 8358"] RD, I looked up loading data in my fourth edition Hornady manual and it lists 62.2 grains of H1000 as a start load for this bullet in this cartridge. Just how flat are the primers? Are there shiny spots or areas on the case head? Have you shot this rifle since you removed the chamber burr, and if you have, is the extraction/bolt lift stiff? If you could post some pics of the fired cases it might help see if there is a problem. You can check the maximum OAL in your rifle's chamber by using a spent piece of brass and a new bullet. With your hand crimp the mouth of the case by pushing it against your bench and then with your fingers start the bullet into the case mouth just enough that it won't fall out. Then carefully start the case w/bullet into the rifle chamber and carefully close the bolt. Then carefully extract the case with your hand. Then with your caliper measure the mock cartridge. This measurement minus .010" will be the max COAL length in your rifles chamber, and that is the length I would recommend loading these bullets. [/QUOTE]
